Construction form plug for nail

Abstract

A low cost, durable, easily reuseable construction form plug (10) is provided to secure a nailed board (42) to the top of a construction form (38). The form plug (10) preferably includes a body (12) presenting a plug end (16), a flange (18) and a bore (30). The plug end (16) is inserted into a hole (35) within the construction form (38), a nail (40) is then driven through the bore (30) so as to engage the board (42) so that the board (42) is securely fixed to the form (38) thereby raising the effective height of the form (38) for purposes of pouring concrete (46) and the like. The plug end (16) includes a circumferential rib (20) which extends radially slightly beyond the radial periphery of the plug end (16) proper. In particularly preferred forms, the form plug (10) is composed substantially of 20% high density and 80% low density polyethylene.

I claim: 
     
       1. A construction form plug for engagement with a construction form presenting a hole for insertion therein and for receiving a fastening member axially therethrough comprising: a plug end presenting a substantially cylindrical sidewall and a substantially planar top end, said plug end having a diameter to height ratio of about three to one, said cylindrical sidewall presenting a circumscribing rib extending radially outwardly therefrom, said rib being located on said plug end and complimentarily sized with said hole for insertion therein with said rib in engagement with a surrounding portion of said form, the height of said plug end being less than the depth of said hole; and   a flange portion of a greater cross-sectional area than said plug end presenting a substantially flat surface for engagement with a portion of said form surrounding said hole and an opposite bottom end presenting an annular lip and a support member spaced radially inward therefrom defining an annular groove therebetween, said support member and groove being located at said bottom end of said plug opposite said top end, said flat surface of said flange portion extending substantially perpendicular to said sidewall of said plug end and substantially parallel to said top end,   said flange and said plug end defining a centrally located bore extending axially therethrough, said bore being of a constant diameter adapted for slidably receiving a fastener therein, and being defined radially inwardly of said support member, said support member presenting a thickness defined by said bore and said groove, said thickness being greater than said bore,   said plug being unitarily formed of a mixture of high-density polyethylene and low-density polyethylene in a ratio of about one to five.
